All the Best, 

actually having the same problem. The 2FA is working for log in, but when I try to use it for the developer console and create a new private/public key, it does not work.

I am having the same issue, where the 2FA using an authenticator app (duo) works for login, but does not work to create private/public key. Please assist!
